Patented Sept. 16, 1930 VINCENT om'rELLo, or READ-virgin,fmnssncnusnir'rs- TRACK-CLEARING nnvrcn) 1 Application filed November This invention relates to new and useful improvements in devices for clearing trackways of snow, ice and the like, and aims to provide a high speed burner unit adapted to s be associated with a flat car movable upon the track and whereby the burner unit may be directed by the workman to any point upon or adjacent the track to melt all snow and ice therefrom, and especially at the switch An important object of the invention is to provide a device of this character that is extremely simple in construction and inexpensive to manufacture, and onethat may be operated at minimum expense.

' With the foregoing and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts to be hereinafter more fully set forth and claimed.

In the accompanying drawings wherein like reference characters indicate'correspondin parts throughout the same:

union or coupling that comprises an essential feature of the burner unit.

As intimated in the statement of invention, my improved burner isadapted to be used in conjunction with a mobile track clearer for melting snow and ice accumulated on the track or adjacent thereto. I As is well known in the art, such track cleaners usually embody a platform movable on the track and on the car is mounted a suitable fuel tank, the contents of which may be discharged therefrom by air under pressure to be conveyed through one or more suitable conduits, which conduits, at their free ends, are provided with burner units for directing a flame against the track for melting the accumulation of snow or ice. In the present illustrated embodiment of the invention, the burner unit is designated generally by the reference char- 59 acter 12, and is adapted to be connected with Figure 8 is a sectional View, through a 3, 19 28. SeriaI No. 316,990.

one end of the aforementioned flexible conduit in a rnanner hereinafter made manifest. The burner unit 12 consistsof an elongated fuel conveying'pipe 12"',,one end of which is adapted to be coupled tojth'e free'endbf a '65. flexible --fu el conduit (not shown), and leading'from a suitable-source of supply '(not shown) and adjacent its freejend, said pipe l2 merges into a coil 13." The outer end convoluteof the coil 13 merges into a substantially straight rearwardly extending portion, said portion extending substantially parallel to the coil, and at its free endterminates substantially parallel to the fuel'conducting pipe 12 as shown to advantage inFigurel; An el bow coupling 14 is attached to the free endof 1 the straight portion of the endmost'coil, while a pipe 15 has one end threaded into the'coupling 11- and-at its other end is suitably coupled to a pipe 16, the last mentioned pipe 16 extending forwardly through and arrangedv concentrically within the coil 13 'as:isalsoshown to advantage in liigure 1. Located upon the forward end of this nozzle pipe 16-is a'suitable burner tip 17, which burner tip 17" terminates inwardly from-the adjacent end of the coil 13, as shown to advantage in Figure 1. 2 Obviously by: reason of the location of this tip the 'fiame therefrom will create heat"- within-the coil 13 for substantially vzip'oriz ing the fuel flowingthroughs'aid coil.

' The intake pipe of the coil designated '12 is equipped with a control valve 19,:while associated with the inner end of this pipe and extending forwardly and diagonally with respect thereto isa brace pipe 20, the forward end of: which is'associat'ediwith the said coupling 14, seeFigure 10. Between this brace pipe 20 and the pipe 12 of the burner unit is a transverse brace pipe 21.

In view of the foregoing description when considered in conjunction with the accompanying drawing it will be apparent that I have provided a novel, simple and useful track cleaner that is well adapted for all the purposes heretofore designated, even though I have herein shown and described the invention as consisting of certain detail structural elements it is nevertheless to be understood that minor changes may be made therein without departing from the spirit of the invention or the scope of the a pended claims. Having thus described the invention, what I claim as new and desire to secure by Letters Patent is:

. 1. In a burner of the character described, an elongated fuel conveying pipe, said pipe being adapted to be connected atone end to a suitable source of fuel supply, said pipe adjacent its opposite end merging into a coil,

the forward convolute'of-said cOil terminating in a straight extending portion extending exteriorly of and in parallelism to said coil,

a second fuel conveying. pipe extending V through the coil and arranged concentri cally therein, a burner tip on one end of said secondmentionecl fuel conveying pipe, a pipe connectedat oneend'to the other. end of said second fuel conveyingpipe, said pipe. at its opposite endconnected to the terminal ofzthe said extending portion of saidforward con- 1 volute, a couplingmembe'r connectingrsaid opposite end ofthe last mentionedpipe to the terminal of-the coil extension, a brace pipe extending from said coupling; member, and securedtothe first mentioned fuel c011 veyingpipe,at its free end, at, a point remote from/ said coil, and a second brace. member secured at onepend to the first men-o 0 tioned fuelconveying pipe, and'atits oppo; site end to, the first mentioned brace memher, said second brace member constituting. ahandle for'the burner.

2. Ina burner-10f the class described, an=

5 elongated fuel conveyingpipe, a coil at the, forward s end of said pipe, a second fuel conducting pipe extending longitudinally, through the center of the coil and having communication with the foremost convolute,

40 of the coil, a burner tip located upon the:

forward end of said longitudinally extending fuel conductingpipe inwardly. from the, adjacent end of said coil, a bracepipe se: cured at one end to-thefirst-mentioned fuel conducting pipe remote from thecoil, means for securing the other end of said brace pipe? to the coil rearwardly of the coil, and a transverselyuextending brace member between the, brace pipeand the first mentionedfuel con a 5" ducting pipe, to provide aohandleoforithe burner.
